  • Direct visualization and characterization of the influence of nanoscale organization on the reactivity of organic functional groups in solution remain a challenge. Here, the authors report the real-time observation of the involvement of a nanostructured reagent in a cross-coupling reaction using advanced liquid-phase electron microscopy.

  • A Ni/NHC-catalyzed strategy for C5-H alkylation and alkenylation of furan- and thiophene-2-carboxaldehydes with alkenes and alkynes has been developed, leveraging an easily installable and recyclable N-PMP imine protecting group. This group suppresses unwanted benzoin condensation of the reactive aldehydes and avoids NHC trapping in Breslow intermediates—a key catalyst deactivation pathway.
